↓ Full nutrition💚 Why it's loved

⚠️ Watch-outs & how to enjoy it better
With 53 grams of sugar per 100 grams, it can cause rapid blood-sugar spikes and is not suitable for those managing diabetes or seeking low-sugar diets. It's also high in saturated fat and contains common allergens like wheat, milk, and soy; to mitigate, pair a single bar with a source of protein (like nuts) and practice strict portion control.

FAQ
Is Twix considered a cookie or a candy bar?
It's officially classified as a 'cookie bar' by its manufacturer, Mars, because it features a baked shortbread cookie base as its foundational layer.
Why does the caramel sometimes separate from the cookie?
This can happen due to temperature changes during shipping or storage. The caramel can soften or the cookie can become slightly stale, reducing adhesion.
Are there different varieties of Twix?
Yes, common variations include Twix Caramel, Twix Peanut Butter, and Twix White Fudge, each altering the primary filling or coating.
